Fixes timing bug that caused Allies to lose when 40 seconds remain and dynamite is planted. Attempts to fix the ship-damaged-while-blowing-boulder bug where the ship gets messed up. Not sure if bug #2 is totally fixed, it needs some testing on busy servers. Adds progressive forward spawns as the boat advances, first the docks, then the ammo drop zone....making that hellish long walk shorter, and making it easier for Allies to advance the boat/capture the CP bunker.
